I bought this for our two newly adopted kitties and they absolutely love it. It was relatively easy to assemble and is very heavy and sturdy. The only problem is that the screw hole for the top circle thingy was just a hole without the threads so the provided screw did not work. I did however have a longer screw and bolt that worked, but I removed the circle anyway because my two rugrats have more fun climbing on the pole to the top platform and couldn't do that with the circle in the way. This is definitely worth the price and the fun my kitties have on it is priceless.
